Paper Abstract

The basic geometrical considerations of microdensitometer optics and a comparison of two major techniques utilized in present instruments are described. These techniques are the "moving sample" method where readings are made on the optical axis of the system, and the "moving image" method in which the sample is scanned electronically or optically. The problems of programming microdensitometer operations for automatic data reduction systems will be discussed.
